The disciples were instructed to move from house to house and search for the one who would be “worthy”. In other translations they were to look for a “man of peace”. This individual would welcome the disciples into their home, family, and lives. As the disciples entered into their house they would have an opportunity to see a whole family changed by the kingdom message. If they were not received, they were instructed to dust off their feet and move to the next home or village.
